Description

technical field

[0001] The invention relates to the technical field of AC metal-enclosed switchgear, in particular to a medium-voltage cabinet with double circuit breaker chambers for safety. Background technique

[0002] At present, similar power distribution equipment on the market mainly includes the following products:

[0003] The domestic GG1A cabinet is remodeled, the double circuit breakers are fixedly placed, and the disconnecting switch is used for the breakpoint. However, this kind of product has a simple structure and does not have the "five prevention" functions. It only has a simple mechanism to prevent misoperation, which has poor safety. The circuit breaker is fixed and placed, and daily maintenance is inconvenient. The cabinet body is welded with angle steel, which has low production efficiency and poor aesthetics. It is now rarely used and is an obsolete product, and existing products are gradually being replaced.

[0004] For Mitsubishi, Fuji and other J...
